They are reminiscent of Logitech's well known "Trackman Marble FX" which was discontinued many years-ago. Those were the best shape a trackball was ever made in, but they just stopped making them. They were so good I never forgot, and when I was recently looking at trackballs, I was happy to find this, and a few others, using a very similar shape to the Marble FX.So I ordered one. It was a wired version, and aggressively low-priced. While Logitech knows it's finger-controlled trackballs are popular, after having some sort of patent dispute and needing to discontinue the lovely "Marble FX," they continue to this day to make the smaller, less lovely "Trackman Marble." This is NOT the same as the "Marble FX," which is no longer made. But it's worth noting, I went through at least four "Trackman Marbles" over the years, wearing them out using them every day, and they always cost about thirty dollars - Logitech has now raised the price of that mediocre offering ... the Trackman Marble, to one hundred and eighty dollars USD. Wow!!... while some innovative companies are actually daring to imitate the beautiful but patent-issue-plagued original "Marble FX" for the first time! I counted three different products, branded differently with some small differences, but they are all basically the same, all clones of a Marble FX.How refreshing! I bought a second one!Before the first one even arrived!The second one I bought is this one, with wireless features. I have it plugged into USB on a Mac Studio desktop*so it will stay charged up, and when my trackpad nags me about charging it, I can just swap that USB cable out of the front of the trackball. Working great so far. It does seem to have a "give me a second" wake-up feature, probably owing to the fact it's wireless so it goes to sleep after awhile. So I just shake it around and it wakes up.This trackball has five resolutions accessible by pressing a button on the bottom of it, and I found a middle value to work well for me. It paired easily with bluetooth. In the hand, it feels comfortable and reminds me of the "correct" trackball design I missed so much from years past! The ball (I got a red one) is big enough and there are buttons galore. I have only used right-click, left-click and there's a nice wheel to scroll.There's a half dozen more button-programmable things I haven't fiddled with. But when I rest my hand on it, my thumb appropriately falls onto the left-click button (which is important!), which has the largest button-surface of all the buttons on that side. It's easy, comfortable and starting to feel like home.*I'm using this with a Mac Studio. It's plug and play, and is working wirelessly with the dongle never removed from its underside (it's using Bluetooth, while that dongle is for 2.4 GHz direct wireless to USB). I have a trackpad AND trackball (a great way to roll) and having just left-click and right-click buttons working out of the box, and the scroll wheel too, is all I'm going to need. I can't comment on usability of the other buttons with a Mac.Maybe I'll try that later.I'll keep both of them. These are WELL WORTH the price (currently under $50 USD). Note from my experience using both this and one of the others that look just like it, they appear to be nearly identical, and there was at least one more I didn't buy which looked also nearly identical. So if you're going for the shape and feel, you'll probably be quite happy with any of them. This one is darker black than the other and has a more velvety surface texture.I'd recommend buying one of these even if you weren't intending to replace your mouse or trackball right now; you'll be glad you did. I had a long history of mouse-caused-wrist-pain which was relieved when I switched to using a finger-manipulated-trackball. I can't recommend this product highly enough! :) ### ⭐⭐⭐⭐⭐ Fantastic Trackball *by on Reviewed in the United States July 15, 2026* I have used a large ball Logitech trackball (rollerball) or decades, and it finally wore out, so I was challenged in finding something similar that had a similar ergonomic feel as well as a button layout. This trackball is super similar to what I had been used to and works great. It is wireless and easily rechargeable using a USB-C connector cable. It is super easy to clean and to customize to the feel and speed you desire, and can be connected to different devices wirelessly or with a USB cabled connection. It holds its charge well, and alerts you when it is time to be recharged.My only challenge has been with the left thumb button as my old trackball had a longer button that was further forward on the trackball, so I had to retrain my thumb on how to use this new trackball, which I am finally and comfortably able to do. I highly recommend it. ### ⭐⭐⭐⭐ Initial impressions - Very Impressed *by on Reviewed in the United States January 8, 2024* So using this trackball for the first 10 minutes and I'm extremely impressed. Im coming from an Elecom HUGE wireless model and this trackball blows that one out of the water.Pro's:Build quality. It feels VERY sturdy. Especially compared to the cheap feeling of the Elecom plastic. (i dropped my Elecom HUGE off my bed one time onto carpeted floor and 2 buttons snapped off.) The plastic case has an extremely comfortable almost soft rubber finish coating on it. Hard to describe but doesn't feel like its plastic. Ball is extremely smooth. Ball pops out easily but doesnt fall out holding it upside down. I'll go as far to say its the smoothest trackball movement I've ever used. And i've been using trackballs for over 20 years.Button layout / Triggers / Scroll wheel - The buttons are quiet but not completely inaudible. Scross wheel is smooth with a good tension as to not accidentally scroll when not intending to.Non programmable buttons. With my Elecom HUGE you could program the buttons but most the time they didn't work correctly in almost all applications, making the extra buttons useless for me.Ease of installation. Plug N play using the USB dongle. Also paired right up to my phone.Auto off feature. Mouse turns off after 30 minutes of inactivity. Wish this time was a little shorter say maybe 10-15 minutes but not a deal breaker.DPI settings. The 5 different DPI modes allow for extreme precision if needed and fast enough to zoom all over my ultrawide monitor with ease.PRICE. This is by far the most affordable trackball I've ever bought and the features/build quality/feel is better than almost every trackball I've ever used.Con's:Even if you turn off the light, it still lights up when moving the ball, but it's very dim so not a huge deal.That's all I can think of for now.__________________________________________________________________I'll update this review with battery life once I reach a point where I'll need to recharge it.If you're looking for an affordable wireless fingertip style trackball, this is a no-brainer. Im debating buying a couple just to have as backups they're so affordable. ## Frequently Bought Together - Nulea M505B Wireless Trackball Mouse, Rechargeable Ergonomic RGB Rollerball Mouse, Easy Index Finger Control with 5 Adjustable DPI, 3 Device Connection for PC, Laptop, iPad, Mac, Windows, Android - Nulea Wireless Ergonomic Keyboard, Split Keyboard with Wrist Rest, USB-C Charging, 7-Color Backlight, Natural Typing, Bluetooth and USB Connectivity, Compatible with Windows/Mac - Nulea Wireless Ergonomic Trackball Mouse, Rechargeable, Bluetooth Rollerball Mouse, 44mm Index Finger Trackball, 5 Adjustable DPI, Compatible with PC, Laptop, Mac --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/533847214-nulea-wireless-trackball-mouse-ergonomic-rgb-44mm-index-finger-control](https://www.desertcart.co.za/products/533847214-nulea-wireless-trackball-mouse-ergonomic-rgb-44mm-index-finger-control) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-08-16*
